Dialog Semiconductor extends partnership with SiFive

Dialog Semiconductor has announced that it has extended its partnership with SiFive, the industry leader in RISC-V processors and silicon solutions

Dialog is SiFive’s preferred power management partner for its HiFive Unmatched, a PC form-factor RISC-V Linux Development Platform for the SiFive Freedom U740 RISC-V SoC.

The HiFive Unmatched platform uses Dialog’s integrated DA9063 system PMIC which incorporates 6 DC-DC Buck Regulators and 11 LDOs. The device enables the SiFive platform to achieve maximum performance by optimally meeting all power supply requirements. In addition, it supports Dynamic Voltage Scaling (DVS) which helps to dramatically reduce the power dissipation and thermal footprint of the platform.

“Our partnership with SiFive is delivering cost effective, power efficient platforms for the benefit of SiFive’s customers and eco system partners”, said Tom Sandoval, Senior Vice President, Automotive Business Segment, Dialog Semiconductor. “The HiFive Unmatched platform is a great example of the power efficiency and performance our DA9063 device can enable."

“RISC-V users demand entry level to high-end multi-core SoC based development platforms with advanced power management features for software development and IP evaluation,” said Chris Jones, Vice President of Products, SiFive. “Dialog’s PMIC solutions allow SiFive to reduce the number of required power management ICs and reuse the same ICs across all of the SiFive development platforms resulting in reduced engineering effort with bring-up, lower cost and a smaller PCB footprint.”

The flexible and scalable DA9063 system PMIC incorporates a built-in configurability engine that provides system designers with the ability to easily solve issues around power sequencing, thermal, and system control.

An intuitive GUI (Smart Canvas) simplifies the customisation to achieve an “exact fit” power management solution, resulting is a highly optimised, cost-effective power management solution that enables a competitive, differentiated system design.
